Press Release.


PlayMining, the issuer of DEAPcoin (DEP), has announced a joint development project with TV Tokyo and a new IP project, “Ishi to Hoshi -Stone Stars- powered by GPT-4”!

By combining ChatGPT with Web3, PlayMining has created AI VTubers that can be “raised by everyone”, which will also appear on broadcast television programs.

SINGAPORE, June 30, 2023 — Digital Entertainment Asset Pte. Ltd. (DEA), a Singapore-based global GameFi company and owner of the PlayMining gaming platform, has announced the joint development of a new intellectual property (IP) project called “Ishi to Hoshi -Stone Stars- Powered by GPT-4”, which utilizes Generative AI, ChatGPT and NFTs. DEA plans to launch the service this summer with the goal of expanding it globally.

Last October, DEA and TV Tokyo formed a strategic capital business alliance with the objective of creating new IPs for global utilization. Employing the latest generation AI technology—which is currently experiencing incredible development around the world—with DEA’s specialty field of NFTs, they are launching “Ishi to Hoshi -Stone Stars- Project Powered by GPT-4” which will implement AI virtual idols that can be co-created by users through input prompts. Ken Kajitani (Representative of POSTS Co., Ltd.), a first-class expert in cutting-edge technologies and product strategies, is also participating as an advisor.

Project Overview 

■ About “Ishi to Hoshi Project -Stone Stars- Project Powered by GPT-4”
“Ishi to Hoshi -Stone Stars- Project powered by GPT-4” is an interactive endeavor featuring AI VTubers that can be co-developed by users. The aim is to cultivate “stars” from their initial stages by developing seven distinct AI VTubers designed around the concepts of “minerals” and “stars,” each with their own unique personality. Users have the opportunity to become producers by acquiring a “Producer NFT”, enabling them to utilize ChatGPT on a dedicated platform to shape the AI VTuber’s personality and profile. Additionally, DEA plans to establish connections with broadcast television programs in the future.

Producer NFTs are tradable NFTs issued by DEA that can also be used as items in the JobTribes NFT game on the company’s PlayMining GameFi platform. Pre-sales are scheduled for July 2023.

■ Comment by Daigo Hirayama, General Manager, New Business Development Office, TV Tokyo
I am truly delighted to be able to announce this new form of ‘AI Vtuber that everyone can develop together’ with such speed. We are looking forward to the project with great anticipation, not only from DEA but also from Mr. Kajitani, who is at the forefront of AI. During my time in the production department, I have planned, directed and produced ‘Can I Charge Tetsuro Degawa?’ and ‘Ariyoshiiieeeee!’, and I believe that user experiences are essential for content from now on. We hope you will join us for a new creative experience that goes above and beyond what is possible, only at TV Tokyo. Please look forward to it.

■ Comment from Kenji Kajitani, Representative Director of POSTS
In the new era brought about by Generative AI, the way content is created and consumed will change drastically. With that in mind, I am very excited to be able to participate as an advisor in the serious ‘Generative AI x Web3’ project launched by TV Tokyo and DEA. In the rapidly evolving Generative AI field, the balance between ‘realization speed and experience quality’ is becoming increasingly important. Therefore, I will leverage my expertise in Generative AI and product design to provide comprehensive support to the project team.

■ Comment from Kozo Yamada, Founder & Co-CEO of DEA
We are thrilled to finally unveil our concept of “developing new content IPs with a globally applicable Web3 approach”, which we have been planning since our capital business partnership with TV Tokyo last October. Since GPT-4 was officially announced in March this year, we have been utilizing the dramatic evolution of AI technology to create a ‘Web3-like’ and ‘TV Tokyo-like’ user-participatory virtual human project. Of course, we will also make full use of PlayMining’s NFTs. We are confident that it will be a new creative experience for everyone, so please look forward to it.
